Abstract
Mild Cognitive Impairment of the Amnestic type (MCIa) is often characterized as an early stage of Alzheimer's Dementia (AD). The P2, an electroencephalographic (EEG) component of the flash visual evoked potential (FVEP), shows an increase in latency for those with AD or MCIa when compared to a group of age-matched controls. The present investigation examined the diagnostic accuracy of several FVEP-P2 procedures in distinguishing people with MCIa and age-matched controls. Participants were exposed to a single flash condition and five double flash conditions with varying inter-stimulus intervals. Significant group differences were observed in the single flash and two of the double flash conditions. One of the double flash conditions, 100 milliseconds (ms), displayed a higher predictive accuracy than the single flash condition, suggesting this novel procedure may have more diagnostic potential. Results from the present investigation lend support to the theory, which holds MCIa as an intermediate stage between normal healthy aging and the serious pathology of AD.
